thermal/drivers/qcom-spmi-temp-alarm: Enable stage 2 shutdown when required

2025-08-20T16:35:55+00:00

[ Upstream commit f8e157ff2df46ddabd930815d196895976227831 ] Certain TEMP_ALARM GEN2 PMIC peripherals need over-temperature stage 2 automatic PMIC partial shutdown. This will ensure that in the event of reaching the hotter stage 3 over-temperature threshold, repeated faults will be avoided during the automatic PMIC hardware full shutdown. Modify the stage 2 shutdown control logic to ensure that stage 2 shutdown is enabled on all affected PMICs. Read the digital major and minor revision registers to identify these PMICs.

thermal/drivers/qcom-spmi-temp-alarm: Drop unused driver data

The platform device driver data has not been used since commit 7a4ca51b7040 ("thermal/drivers/qcom-spmi: Use devm_iio_channel_get") so drop the unnecessary assignment.

thermal/drivers/tsens: Add TSENS enable and calibration support for V2

2025-03-25T19:52:03+00:00

SoCs without RPM need to enable sensors and calibrate them from the kernel. The IPQ5332 and IPQ5424 use the tsens v2.3.3 IP and do not have RPM. Therefore, add a new calibration function for V2, as the tsens.c calib function only supports V1. Also add new feature_config, ops and data for IPQ5332, IPQ5424. Although the TSENS IP supports 16 sensors, not all are used. The hw_id is used to enable the relevant sensors.

thermal: Switch back to struct platform_driver::remove()

2024-11-13T15:17:57+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/thermal to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way make a few whitespace changes to make indention consistent.
